Sonographically guided costotransverse joint injections: a computed tomographically controlled cadaveric feasibility study.

Objectives: The primary purpose of this study was to describe and validate a novel sonographically guided costotransverse (CTRV) joint injection technique.

Methods: The bilateral T3-T10 CTRV joints of an unembalmed cadaveric specimen were localized using a 12-3-MHz linear array transducer. A 22-gauge, 2.

Utility of ultrasound-guided near-nerve needle recording for lateral femoral cutaneous sensory nerve conduction study: does it increase reliability compared with surface recording?

Introduction: The aim of this study was to assess the reliability of a near-nerve needle recording technique in lateral femoral cutaneous nerve (LFCN) sensory nerve conduction studies (NCS).

Methods: Bilateral LFCN sensory nerve action potentials (SNAPs) were recorded from 10 healthy volunteers using surface and near-nerve needle recording electrodes. Absolute amplitudes were compared side-to-side in each subject and between the 2 techniques.
